The Avid Attic is Avid Media Composer's built in back-up feature. You can think of this space like an autosave feature for your bins. If something goes wrong with your project and you lose progress, you can copy bins from the attic on the computer you were using to revert to an older version.
Finding the Attic
Hide Media Composer.
Navigate to the following folder
Macintosh HD/Users/Shared/Avid Media Composer/Avid Attic folder.
Copying a backup from the Attic
The Avid Attic will display a folder for each project opened on the computer across all users.
If you are not already, use List view. This will make it easier to navigate the Attic.
Open your project folder, and then open the Bins folder.
The Bins folder will contain a folder for each bin in the project.
Open the folder for the bin you want to retrieve.
The bin folder displays all of the backup bin files and their creation dates. A backup bin file has the same name as the bin, with a number appended. For example, a bin named Source Clips might have backup bin files named Source Clips.1 and Source Clips.2. Use the creation date of the files to locate the backup that you want to use.
Option+drag the selected backup bin file to the desktop. This makes a copy of the file, leaving the original files in the Avid Attic folder.
On the desktop, rename your file (right click, rename) - remove the number at the end and replace it with .avb (example: "Sequences.4" is renamed to "Sequences.avv")
Bringing your Backup into your Project
Open Avid Media Composer.
Make sure the old version of your bin is closed. Media Composer does not allow a bin and copy of a bin to be open at the same time. You must keep all other bins closed and open the backup bins one at a time.
File > Open Bin.
In the finder window, navigate to the desktop, select the backup bin files you copied, and click Open.
The backup bin opens. When you open a backup bin, a link to the backup bin on the desktop is created in the Other Bins folder. The Other Bins folder is not a safe place for us to work out of - we need to move the data into a new bin inside our project folder.
Create a new bin and name it something different than the original bin. For example, if you are retrieving clips from a backup bin called Sequences.2, you can call the new bin Sequences New.
Open the new bin and open the backup bin in the Other Bins folder. You will see them in two tabs.
Select the material you want to keep from the backup bin, and drag it into the new bin.
Once you are finished, select and delete the backup bins in the Other Bins folder.
Drag the backup bin files on the desktop to the Trash.
Now, you can continue working on your project.
